Abstract

Clustering and transmission range adjustment are major
approaches to energy saving in wireless sensor networks.
Connected dominating set (CDS) as a special clustering
structure. is widely used as a virtual backbone ill a wire
less sensor network. In clustered wireless sensor networks
traffic: load has a great impact on the energy saving ef
fect of a clustering algorithm. This paper presents RDSP
CDS a traffic-adaptive clustering and transmission range
adjustment algorithm. range a distributed clustering
algorithm that utilizes our energy, analysis model [l]. In
range , each node chooses the optimal transmission
range based on its local knowledge about the traffic load to
achieve network-wide energy saving goals. range is
suitable for heterogeneous dynamic-topology networks
